Maritime sector use case

The objectives for tracking the position of the vessels are twofold: increase the safety and security within the maritime sector.
In order to address maritime use cases, the Moving Feature standard has to include at least the following information: i ship position, which can be provided by different data
source AIS, LRIT, etc …; and ii ship voyage, which describe the track of a ship. Additional information about the vessel incidents and the ship particulars has to be
considered optional and therefore as possible extensions to the Moving Feature standard. For example, the following figure summarize the information collected by the Canonical
Data Format produced by the European Maritime Safety Agency
Figure 6.8: Canonical Data Format
The following map reports the last position of vessels within a specific area black triangle, and the track of a specific vessel yellow triangles. In this case the yellow
triangles report the position of a specific vessel every 6 minutes in the last 24 hours. Furthermore additional information as: heading, true heading and speed is recorded to
enrich the description of the vessel track.

A vessel has a unique identification at worldwide scale IMO number, or MMSI. The position of a vessel ship position is a point feature over the time. The voyage feature of
a vessel ship voyage is characterized by several attributes: speed over the water, course over the water, heading and true heading.
In conclusion, to build the trajectory of a vessel two main abstract feature types are relevant for Moving Feature standard: ship position and ship voyage.
